I use hazelcast 3.5.1 and got this exception,How can I fix it?

That is a strange error.

Can you post your JVM version?
Can you post the full classpath? Perhaps you have some Xalan jars on your classpath that might cause conflicts (wild guess)

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

hazelcast-3.5.1.jar hazelcast-cloud-3.5.1.jar and xalan-1.3.jar

@wmz7year , this is known issue for us.. We have completely fixed this issue in 3.6.. For 3.5, we advice some workarounds. Can you please set this system property in your jvm , (also you can pass this property to your jvm as an arg line)

System.setProperty("javax.xml.transform.TransformerFactory",
                "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");

many thanks for feedback and we are waiting your new feedbacks..

@bilalyasar good, it work! My error is
"java.lang.IllegalStateException: You are running with invalid JAXP api or implementation. JAXP api/implementation of version 1.3.1 (included in JDK6) or higher is required. In case you are using ant, make sure ant 1.7.0 or higher is used - older versions of ant contain JAXP api/impl version 1.2 (in xml-apis.jar). If you want to keep using older ant versions, you have to configure it to use higher the JAXP api/impl versions.";
